Reset your regs. I would turn the LPR out to flush with the lpr cap (http://img397.imageshack.us/img397/5263/img5423wm6.jpg)
, then back in 1 1/2 turns in (please let me know if you've heard otherwise...it's been awhile since I've owned an 07). Then thread your inline reg adjustment screw out as far as it will go, then back in 5 turns (to set your pressure intially for velocity adjustment purposes). Now make sure your dwell is set at about 15 ms. Now tune from there. Also make sure your brand name batteries are also brand spankin' new for your tuning purposes. Adjust the inline only for now. You can sweetspot your dwell later. See if this gets you into the 290+ range.
